Precaution
1. The wearing method should be correct. When wearing a mask, try to tighten the elastic band of the mask and compress the aluminum sheets on both sides of the nose to reduce leakage around it. It is best to breathe slowly.
2. The wearing area should be appropriate. Do not wear a mask in a space where the virus may be present, and try to wear it before entering the indoor space.
3. The wearing time should be appropriate. Medical protective masks can be used continuously for 6 to 8 hours, and should be replaced in time when the following situations are encountered: when breathing is difficult; the mask is damaged or destroyed; the mask cannot be close to the face; the mask is contaminated; it has been used in isolation wards or in contact with patients.
4. Perform a fit test after wearing. The simple test method is: After putting on the mask, exhale forcefully so that air cannot leak from the edge of the mask.
5. Do not squeeze the mask with your hands after wearing it. If you squeeze the mask with your hands and let the virus seep into the mouth with the droplets, you still have a chance to get the virus.
6. Do not discard discarded masks at will, otherwise it will cause secondary pollution.
7. Doctors try not to speak or speak less during the operation, and avoid talking or laughing, talking loudly, or coughing or sneezing on the operating table.

1. Surgical masks are single-use, simple in structure and single in function. They can only play a preliminary role in isolation. The trace chemical elements and toxic substances emitted by the drugs or equipment used during the operation cannot be eliminated.
2. The structure of the mask is relatively uniform, and the lanyard cannot be adjusted according to personal wishes. For the surgical process, the continuous adjustment of the mask will have a certain impact on the doctor's surgical process.
3. Discard the mask directly after the operation, causing a certain waste of resources.
4. Because the material of the nose clip is too soft, the position of the nose clip is easy to leak air, and the fit between the mask and the human nose is not high. If the protective mask cannot fit the user's face tightly, harmful substances in the air will enter from the leak. The inside of the mask is harmful to the human respiratory tract.
5. When the doctor sweats on the head during the operation, the mask cannot absorb sweat, the sweat will fall on the operating table, and the bacteria in the sweat will cause cross infection to the patient.
